Power for All Tamil Nadu
Joint Statement
Tamil Nadu is already a pioneer state in
implementing 24X7 Power to all sectors. The
state has already achieved 100% village
electrification level.
The state had witnessed peak surplus in financial
year 2016 and has continued to move with
adequate plans for the surplus power for
forthcoming years.
In addition, The State Government is also
providing free electricity of 100 units bi-monthly
to all category of domestic consumers.
Thus, the Government of Tamil Nadu is
continuously supporting the power sector
through subsidy schemes aimed at supporting
poor and marginal consumers and elimination of
regional disparities in the state.
The State has made significant progress in
expanding access and availability of electricity
over the past. This is complemented by the fact
that the state is one of the leading states in the
country in renewable capacity addition.
This roadmap is prepared with the efforts of
Ministry of Power, CEA and Tamil Nadu utilities
(TANGEDCO and TANTRANSCO). The targets
provided in this roadmap are developed by
dovetailing and utilizing the existing master plan
proposals of Tamil Nadu utilities for infrastructure
addition and capacity development in
Generation, Transmission, Distribution, Energy
Efficiency/DSM and Renewable Energy sectors
to achieve the objectives of the 24X7 Power For
All program for the period FY17 to FY19.
The State Government will put in place
appropriate State level governance those listed
in this document.
The Ministry of Power, Gol would support the
efforts of State on various issues to be dealt with
at the Central Government level including those
listed in this document.
The MoP, Gol shall also endeavor to support the
State in availing concessional financing
arrangements for power utilities in the State.
Though the state has already achieved the
objective of the program, the Central and State
Governments would meet regularly over the next
three years to review and monitor the progress
on the rollout plan for enhancing the infra
structure facilities and to maintain the
satisfaction levels of the consumers and improve
the quality of life of people through 24x7 power
supply.

1. Executive Summary
1.1. Introduction
24x7 Power for All is a Joint Initiative of
Government of India and State Government with an
objective to strengthen the power supply
infrastructure and make 24X7 reliable and quality
power available to all households, industry,
commercial businesses, public needs, agriculture
and any other electricity consuming entity. This
roadmap document aims to meet the above
objectives for the state of Tamil Nadu which is
already implementing 24X7 power supply to all
sector.
As per 2011 census, Tamil Nadu had higher
Household (HH) level electrification of 93.4% as
compared to national average of 67.2%.
There has been significant infrastructure addition in
all the areas of the power sector during the past few
years. As a result of the capacity additions made
towards meeting the demand, the peak deficit for
FY16 was zero and this trend is continuing in FY17.
1.2. Connecting the unconnected
The state has made significant advances in
extending distribution network to un-electrified
households in the last few decades. Due to these
efforts The State has achieved almost 100% village
and HH electrification level as on March 2016,
barring some remote households (5,787) which are
planned to be electrified using off grid solutions.
Growth in demand and 24X7 supply
The state has been maintaining almost 24 hours
power supply to all categories of consumers. The
average supply to agriculture sector is about 24
hours per day. Load shedding prior to 01.06.2014
has been totally withdrawn for all categories of
consumers and continuous power supply is being
extended to all areas of Tamil Nadu. Growth in
demand is expected to be 7%. TANGEDCO
envisages peak demand to touch 17,651 MW by
FY19.
1.3. Generation Plan
The state has an installed capacity of 24,433 MW
as on 31.03.2016. Tami Nadu has one state owned
generation company – TANGEDCO. In addition
there are various central and private generating
companies. By FY17 the installed capacity is
expected to increase by about 2,509 MW from
thermal sources including 165 MW from Co-
generation sources & another 5,100 MW from
Renewable energy sources (Wind, Solar and other
Sources). The expected capacity additions are in
line with the anticipated peak demand projections.
The projects under implementation are on track.
Bottlenecks and constraints of the available linkage
of coal for existing plants have also been addressed
to some extent.
During February 2016 Chandrabila coal block was
allotted to TANGEDCO for ETPS Expansion
project, Ennore SEZ project and Udangudi Stage I.
TANGEDCO has already signed MOU with MMTC for imported coal for following projects:
ETPS Expansion project (2 MTPA, date of signing :23.7.2012),
Ennore SEZ project (4.549 MTPA, date of signing : 26.06.2012),
NCTPP Stage III ( 2.51 MTPA, date of signing 25.05.2015),
Uppur Thermal power project (5.01 MTPA, date of signing: 25.05.2015) and
Udangudi Stage I (3.87 MTPA, date of signing: 19.11.2012).
It may be noted that, TANGEDCO is awaiting coal block allotment from indigenous sources for NCTPP Stage III and Uppur Thermal Power Plants. Expected CoD is beyond FY19 for these two plants.
1.4. Transmission plan
Power for All – Tamil Nadu
Page | 2
As on 31.03.2016, the existing intra state
transmission network comprises of 908 EHV grid
substations with 59,953 MVA capacity along with
30,331.6 ckm associated transmission lines.
Further, the transmission system owned by PGCIL
consists of 8,127 ckm of lines and 9,300 MVA of
transformation capacity. By FY19 the intra-state
transformation capacity is proposed to be
enhanced to 94,217 MVA (which includes
additional 8,640 MVA for Renewable Corridor) and
33,768 ckm of intra-state transmission lines.
The state transmission utility TANTRANSCO has
proposed investments for meeting its anticipated
demand as well as providing connectivity to the
upcoming renewable energy corridors. In this
endeavor, TANTRANSCO has outlined a total
capital expenditure layout of Rs. 20,309 Cr. These
projects are funded by various agencies like PFC,
REC, NABARD, TNIPP, JICA, etc. Further, some
projects for providing evacuation of Renewable
Energy projects are being executed under KfW
funding schemes.
1.5. Distribution plan
The state distribution utility TANGEDCO is in
advanced stages of completing the RGGVY
scheme. Further, the utility has already started
implementing R-APDRP schemes across the state.
In addition to these centrally sponsored schemes,
the utility is also adding network under ADB funded
schemes.
For meeting the network requirement of existing
consumers and extending the distribution network
to the newly constructed HHs, the utility has
proposed enhancement of network by means of
addition in HT network, LT network and additional
power and distribution transformers and various
other improvement works. This plan will increase
the number of DTs from 2,64,029 in FY16 to
320,681 in FY19, similarly the LT network will
increase from 6,09,544 kms in FY16 to 644,603
kms in FY19. These network additions are
proposed with an investment of Rs. 9,348 Cr.
1.6. Renewable energy and energy efficiency
The state has RE installed capacity of 9,687 MW
(Sep 2016). The RE installed capacity is mostly
contributed by wind (7,642 MW) followed by solar
(1,155.4 MW). The state has planned off-grid
renewable solutions to cater to the growth in
demand in far-flung areas with poor accessibility.
This includes 5,787 standalone solar solutions.
Future plans for renewable capacity addition
includes addition of 5,265 MW of renewable energy
through investments by private sector.
State’s energy efficiency plan is already in place. In
the past the utility had provided 8.75 lakh CFLs in
exchange of incandescent bulbs across the state
under various schemes, further schemes include
distribution of energy efficient pump sets.
Load survey for identification of energy saving
potential in various sectors (domestic, commercial,
industrial, agricultural, etc.) across the state is in
progress. Based on the report on load survey, a
DSM action plan will be formulated for maximizing
the use of energy efficient appliances under various
sector wise schemes. TANGEDCO will take up the
schemes for implementation, one by one, subject to
financial viability.
1.7. Financial turnaround
Considering TANGEDCO is able to achieve AT&C
loss reduction targets, a tariff hike of 5.52% will help
the utility to operationally turnaround by FY19.
The State Government is continuously extending
financial assistance to TANGEDCO over the past 5
years. Further, the quantum of subsidy was also
increased from Rs.2,071 Cr. during FY12 to
Rs.6,695 Cr in FY16. In order to compensate
differential cost of supply for the free supply to
agricultural consumers, the Government of Tamil
Nadu has revised the subsidy from Rs.250/HP/p.a.
to Rs.2,875/HP/p.a.
With respect to the restructuring of loans, the
Government of Tamil Nadu has already approved
FRP during FY13 and taken over Rs.6,353.49 Cr.
of loans of TANGEDCO and its interest liability.
Under the FRP, TANGEDCO has restructured
remaining Rs.5,951 Cr. of loan liability with banks
for a tenure of 10 years including 3 years
moratorium. TANGEDCO is also taking various
measures for swapping of high interest loans to low
interest loan for considerable savings in interest
cost.
The Government of Tamil Nadu is also converting
the Electricity Tax recovered by TANGEDCO from
the consumers about Rs.800 crores p.a. so as to
partially help in the financial management of
TANGEDCO.

2.1. The State of Tamil Nadu
Tamil Nadu is situated in the southern peninsula of
Indian subcontinent and is surrounded on the north
by Andhra Pradesh and Karnataka, on the west by
Kerala, on the east by the Bay of Bengal and on the
south by the Indian Ocean. With a population of
over 7 Crore and an area of 130,058 sq.km, it is the
7th largest in terms of population and 11th largest
State in India in terms of area. The state contributes
nearly 8.4% to India’s GDP making it the 2nd largest
contributor, only after Maharashtra.
Urbanization in Tamil Nadu is highest in the country
with urban areas accounting for as high as 48.4%
of State’s population, as against national average
of 31.2%. In terms of households (HHs), Chennai is
the largest district with 11,06,567 HHs. The State
witnessed high HH level electrification in rural
areas, as per Census 2011 90.8% rural HHs have
access to electricity, which gradually increased to
an impressive 100%.
The State has as an area of 1.3 Lakh sq.km with a
gross crop area of around 63,000 sq km (63 Lakh
Ha). The state provides free electricity to
agricultural consumers to boost the primary sector
output of the state.
The State’s mineral reserves and major minerals
include limestone, bauxite, gypsum, lignite,
magnetite, and iron metal. The opencast lignite
mines at Neyveli, in the north-center part of the
state, are amongst the largest in India, and are
utilized to fuel power stations of Neyveli project that
contributes a significant part of the state's power.
Tamil Nadu has a strong presence of
manufacturers of engineering and auto
components, textiles, leather, sugar etc. The state’s

Backed with high industrial and commercial activity,
the State’s per capita electricity consumption of
1,280 kWh (FY16) ranks among the top ten states
in the country.
A significant part of Tamil Nadu's energy is
contributed by thermal stations. The hydroelectric
plants particularly along the Kaveri River and its
tributaries provide options of Hydro Energy. The
state is also a leader in wind-power and solar
generation. A brief overview of the power sector of
Tamil Nadu is discussed in the following sub-
section.
2.2. Tamil Nadu Power Sector At a Glance
Formed in 1957, Tamil Nadu Electricity Board was
constituted as a vertically integrated entity
responsible for power generation, transmission and
distribution. In line with the requirement of
Electricity Act 2003, the entity was restructured into
one holding and two subsidiary companies with
TNEB Ltd. as holding company. The subsidiary
TANTRANSCO Ltd. was created to undertake
transmission in the State, while the generation and
distribution was vested into TANGEDCO Ltd.
Notably, Tamil Nadu is one of the early achievers of
100% village electrification and has the largest wind
and solar power generation capacity across the
country. Over the past few years, the utility has
incurred significant capital expenditure to improve
access and reliability of supply in the State. With the
continued commitment of State Government and
enormous efforts of utilities, the state has overcome
obstacles in generation, transmission and
distribution. A brief snapshot of the state power
sector is discussed in Table 2. In compliance of the
Electricity Act, 2003, the state has restructured the
erstwhile Tamil Nadu Electricity Board (TNEB) with
effect from November 01, 2010 into three entities
TNEB Limited (holding company) and its
subsidiaries:
Tamil Nadu Generation and Distribution
Corporation Limited (TANGEDCO) which is
responsible for electricity generation and
distribution within the state.
Tamil Nadu Transmission Corporation Limited
(TANTRANSCO) which is responsible for
electricity transmission of the state
The State Regulator- Tamil Nadu Electricity
Regulatory Commission (TNERC) was established
and became operational from July 2, 1998. TNERC
carries out its function and roles in accordance with
applicable provisions of the Electricity Act, 2003.

The erstwhile Tamil Nadu Electricity Board has been bifurcated into two subsidiary companies
viz., TANGEDCO & TANTRANSCO and operational w.e.f. 1.11.2010. The entire carried forward
losses of erstwhile Tamil Nadu Electricity Board has been adjusted against the revaluation
reserve created out of the assets revalued to the extent of Rs.34,741.31 crs under transfer
scheme.
Subsequently, TANGEDCO has started with NIL accumulated loss and incurred loss of Rs.5,634
crs in FY11 (5 months). Consequent to the several revenue augmentation and cost control
measures taken up such as replacement of static meters, prompt disconnection of defective
services, stoppage of high cost power purchase from independent power producers, effective
negotiation of power purchase rates under long term contracts as well as import coal rates,
TANGEDCO could be able to considerably reduce financial loss from Rs.12,756.60 crs during
FY15 to Rs.5,787 Crs for FY16.

3. Power Supply Scenario
3.1. Power Supply Position
Tamil Nadu is the 3rd largest consumer of electricity
accounting for nearly 9% of total energy
consumption in India (during FY16). Over the last 5
years, the State has benefitted by the significant
capacity additions and allocations, resulting in
decrease in peak deficit from 6.38% in FY11 to 0%
in FY16. The utility has undertaken several
measures with focus on reduction of T&D losses
and considerable capacity addition which have led
to the improvement in power supply. The peak
demand met in state has increased at a CAGR of
6.4% over the last five (5) years leading to steep
decline in the peak deficit (Nil in FY16). In terms of
energy requirement and availability, It may be noted
that, the Power Supply Position figures in this
document have been provided by TANGEDCO,
these figures vary from CEA figures due to non-
inclusion of state’s own generation injected at STU,
the energy requirement is derived by adjusting the
estimated energy lost due to scheduled outages
and the available energy.
Monthly data for peak and energy shows that during
April’15 to May15, deficit of the order of ~1% was
observed. However, from Jun’15 onwards there is
no shortage in peak and from Sep’15 onwards there
is no shortage of peak and energy. The seasonal
trend of peak and energy shortages for the period
of April’15 to March’16 is illustrated in Figure 2
TANGEDCO has been able to maintain 24 hours of
supply to both urban and rural areas since June
2014. In the current financial year, TANGEDCO has
so far been able to provide reliable supply to its
consumers. During the current year, TANGEDCO
has embarked on supplying 24 hours supply to all
rural and urban consumers. It can be said that
TANGEDCO has already achieved key objectives
of PFA program, i.e. to provide 24X7 electricity to
all its consumers. The other objective of ensuring
electricity access to all consumers has been
already achieved by the State as all HHs in the
State are already connected to the electricity
network.

The PFA program, thus focuses on maintaining
adequate generation capacity with commensurate
transmission capacity and strengthening of
distribution infrastructure to continue supply of
24X7 reliable electricity to all connected
consumers, including industrial and commercial
consumers.
3.2. Consumer and Sales Mix
TANGEDCO is the sole distribution licensee in
Tamil Nadu. At the end of FY16, it had a consumer
base of over 2.6 crores. Substantial quantum of
sales is contributed by subsidized consumer
categories including domestic (30%) and
agricultural supply (15%). This sales mix offers
limited advantage to the utility, as the share of
subsidizing industrial sales is about 35% in overall
retail sales during FY16
This must be seen in light of Tamil Nadu being a
highly industrialized State and a manufacturing hub
for numerous industries. The utility has encouraged
the utilization of open access and various industrial
consumers have shifted to sourcing power through
open access or setting up their own captive
generation units. In FY16 the share of open access
energy in Industrial and commercial sales was
about 29.29%.
Industrial consumers are about 2% of total
consumers, these consumers have the highest
contribution towards energy sales with total share
of 35% as can be seen in Figure 3 . There has been
significant addition in the consumer base across the
categories as inferred from the category wise
consumers and sales growth trend. In terms of
consumers, domestic consumers account for
highest share of 76%, contributing around 30% of
total energy sales.
TANGEDCO has high share of agricultural sales
(15%) contributed by 20 Lac unmetered agriculture
consumers out of total 32 Lacs unmetered
consumers in the State.
3.3. Methodology for Demand Projections

24X7 power to all HHs, the demand projection has
been calculated separately for rural and urban HHs.

growth rate based on TANGEDCO’s estimation of
the expected growth along with a review/ validation
with the past trend has been considered. The
following steps detail out the approach adopted for
estimation of energy requirement for the State.
Estimation of Rural and Urban electrified and
un-electrified HHs
Based on the available census data for 2011,
extrapolated with past 10 years CAGR Estimation
of number of rural and urban HHs are done.
In addition to the level of electrification in rural areas
as per 2011 census data, the actual rural HHs
electrified since 2011 has been considered to arrive
at the present level of electrification. In case of
urban areas, the same level of access as in 2011
census (in percentage terms) has been assumed
on the estimated HH numbers to arrive at the
number of existing un-electrified HHs. Also actual
data of electrification is considered into the
calculation. It is noteworthy that the state has
already achieved 100% electrification of both urban
and rural households. Therefore, there is no
additional energy demand from the electrification of
un-electrified HHs in the State.
Estimation of Energy Requirement from HHs
The energy requirement from domestic category
consumers (HHs) has been estimated using the
end use method under the following categories:
a) Latent demand from existing HHs on
account of increase in specific consumption
(kWh/HH/day) for each of the electrified HH
due to life style advancements and natural
growth;
b) Additional energy requirement due to
construction of new urban and rural HHs;
Latent demand growth from already electrified HHs
has been estimated based on expected increase in
consumption levels in accordance with the
objectives of the PFA program. Accordingly it is
expected that the daily HH consumption in urban
areas will increase from 4.54 kWh in FY16 to 5.10
kWh by FY19. Similarly, daily rural HH consumption
will increase from 1.97 kWh in FY16 to 2.22 kWh by
FY19 as illustrated in Table 4.
Table 4: Per HH per day consumption (kWh)
Particulars FY16 FY17 FY18 FY19
Urban 4.54 4.72 4.91 5.10
Rural 1.97 2.05 2.13 2.22
Since HHs in the state are 100% electrified, no
additional energy requirement will be realized due
to electrification of un-electrified HHs.
However, TANGEDCO has identified 115 nos. un-
electrified remote habitation with a total of 5,787
households. The electrification of these HHs by
conventional mode is not feasible. These
households are proposed to be electrified though
off-grid solutions as they are located in
remote/forest areas. Accordingly, demand arising
out of these HHs is not considered in the overall
demand estimation.
In order to estimate the energy requirement for
newly constructed HHs, the expected number of
newly constructed HHs has been estimated to be
300,000 HHs each per year for both Rural and
Urban areas.
Estimation of Energy Requirement from Other
Consumer Categories
The energy requirement projections from other
consumer categories have been done factoring the
expected natural growth considering the past trend
and current consumption in accordance with the
PFA Roadmap.
The projected demand for different consumer
categories is discussed in the following sub-section.
Power for All – Tamil Nadu

3.4. Demand Projections – TANGEDCO
Based on above steps, the total energy sales for
TANGEDCO is expected to increase by about 7.9%
CAGR from 79,464 MUs in FY16 to 99,753 MUs in
FY19, as presented above in Figure 4. Even with
the expected addition of new HHs and increase in
specific consumption, the percentage share of
energy sales to domestic consumers is expected to
remain stable at nearly 30-40%.
Increase in total energy sales is also attributable to
other than domestic sales, which is expected to
grow at a CAGR of 7% during the period. It can also
be observed from Figure 4, that in line with the sales
to domestic category, the share of energy sales to
other than domestic category consumers is
expected to remain in the range of 60-70%.
TANGEDCO had wheeling sales of about 10,835
MU in FY16. While estimating the future sales from
other than domestic category the wheeling energy
is projected to be 24.3% (FY16 share) of other than
domestic sales. Consequently, the wheeling sales
is expected to increase from current level of 10,835
MUs FY16 to 13,273 MUs in FY19. Accordingly, the
peak required for the wheeling sales have been
projected to increase from 2,007 MW to 2,458 MW
(based on FY16’s estimated peak required for
wheeling sales) for the period FY17 to FY19.
The share of energy requirement from both urban
and rural HHs is projected to grow significantly in
the future. The share of rural HH sales in the sales
to domestic consumers which is about 30% in FY15
is expected to remain almost same in FY19 as can
be seen in Figure 5.
In order to estimate the energy input requirement at
the state periphery, distribution losses and intra-
state transmission losses have been considered.
The energy consumption estimated above
translates into energy requirement at state
periphery, as can be seen in Table 5. It may be
noted that export to Puducherry (about 187 MU) is
included in sales.
The energy requirement at the State periphery (for
retail sales) is likely to increase from 85,926 MU in
FY16 to nearly 1,04,214 MU in FY19. Peak demand
for power has been derived using the actual load
factor for FY16. Accordingly, Peak Demand for
retail sales is expected to grow by about 17% from
FY 16 FY 17 FY 18 FY 19

12,526 MW in FY16 to 15,192 MW in FY19. The
peak demand due to wheeling consumption is
estimated by using the corresponding wheeling
demand using FY16 values, Total peak of the state
including wheeling energy is expected to increase
from 14,533 MW in FY16 to 17,651 MW in FY19.
Projected energy requirement including wheeling
sales in MU (1,17,487 MU) terms is expected to fall
short of the 18th EPS estimates (1,37,815 MU).
Similarly, the projected peak demand in MW is
expected to fall short of the 18th EPS estimates.
The difference in the peak demand projections is
due to the load factor used in the 18th EPS (65% in
FY16) vis-à-vis the actual load factor witnessed
(78.3 % in FY16).The projected energy requirement
and the peak demand projections up to the period
FY19 are expected to remain much lower than the
18th EPS projections. A comparison of the projected
figures under the PFA Roadmap vis-à-vis the 18th
EPS is shown in Figure 6.

4. Generation Plan
4.1. Generation Sector in Tamil Nadu
Tamil Nadu Generation and Distribution
Corporation (TANGEDCO) Limited, a company
owned by the Government of Tamil Nadu, is
entrusted with the goal to carry on the business of
power generation and distribution in the state. The
state draws power from its generating stations,
private producers including renewable energy
generators and has allocation from Central
Generating Stations. The details of existing
installed state owned generating capacity and PLF
for FY16 is provided in Table 7.
The total installed capacity in the state, (including
own generating stations, IPPs and central
allocation) is 24,433 MW. Table 6 shows the sector
wise break-up of the installed capacity. The share
of thermal stations in the installed capacity stands
at 51%. The State sources contribute to 31% of
installed capacity (51% excluding RE Sources),
whereas the private sector comprising of mostly RE
sources contributes 39% of the installed capacity.
Break-up of the installed capacity by ownership and
source is provided in Table 6.
During the period FY16 to FY19 the peak demand
(including wheeling demand) and energy
requirement (including wheeling sales) is expected
to increase from 14,533 MW and 1,00,319 MU in
FY16 to 17,651 MW and 1,17,487 MU in FY19. In
order to meet this increase in demand, the state
needs to plan for either development of its own
generation capacity or tie up with central generating
stations/ IPPs. This chapter describes the
readiness of the state for meeting the projected
power demand scenario and highlights the future
plans and forward in view of the gaps and issues
identified therein.
Tamil Nadu’s power demand is mostly met by
TANGEDCO and Private Players in the state (78%
of the total installed capacity). The State’s own
generation sources (TANGEDCO) contribute to
more than 31% of the total installed capacity in the
state.
Table 7 contains details of the plants owned by
TANGEDCO. The capacity includes approx. 5,176
MW of thermal sources including 516 MW from gas
based stations. TANGEDCO’s hydel generation
sources contribute 2,308 MW of capacity including
123 MW of small hydro plants (SHPs).These SHPs
are discussed in the renewable energy plan chapter
of this document.
4.2. Generation Plan
The generation plan for the state envisages the
proposed capacity additions by the state along with
the allocated share of upcoming central and IPP
generating stations. The generation capacity
addition and power procurement plans have been
aligned with the energy requirement and power
demand assessed in the earlier sections of this
report.
Inter-State/ Central Sector Projects
The state is expecting capacity additions of about
2,509 MW from thermal sources including co-
generation plants and Central sector’s plants such
as NTPC, NLC and NPCIL. The details of these
plants are shown in Table 10. Further, the existing
allocation from Central sector plants are provided in
Table 8.

In addition to the above, the state draws power from
the unallocated shares of central stations. As on
April 2016, 469 MW of unallocated share of central
stations was available to Tamil Nadu
Intra-State/ State Sector Projects
TANGEDCO is undertaking construction of
following four Thermal Power Projects,
660 MW ETPS Expansion project,
1,320 MW Ennore SEZ project,
800 NCTPP Stage III and

4.3. R&M Program
As seen from Table 11, TANGEDCO is undertaking
R&M of TTPS, MTPS, and NCTPS thermal power
stations. The company has availed funds from PFC
and REC for implementing the R&M Projects in the
state. The R&M works undertaken by TANGEDCO
for thermal and hydro projects as depicted below in
Table 11 and Table 12 respectively.
TANGEDCO owns around 3,000 MW of thermal
generating stations which are at least 25 years old.
The utility would benefit from another R&M program
directed towards these stations. TANGEDCO has
requested GoI to evolve specific schemes for R&M
measures to augment generation by providing
financial assistance as grants instead of loan. This
would benefit the consumers as it would help in
reduction in generation cost along with
improvement in efficiency.
4.4. Anticipated Power Availability Position- TANGEDCO
During FY16 to FY19 TANGEDCO is expecting
capacity additions of 2,509 MW through thermal
(conventional and nuclear) sources of TANGEDCO
and CGS (NPCIL, NLC) including 165 MW from Co-
generation sources & another 5,100MW from
Renewable energy sources (Wind, Biomass and
Solar Sources). The contribution of Renewables is
higher than conventional sources as 5,265 MW is
expected by FY19. Major share of energy is
expected from thermal sources (85% of the total
volume available) while 15% is expected from
renewables.
Based on the capacity additions as discussed
above, the installed capacity is expected to
increase to 35,855 MW by FY19 (including medium
and long term procurements). The peak demand
expected in FY19 is 17,651 MW. The available
capacity for the state is expected to be sufficient
and shortages are not expected.

While estimating the energy available, existing PLF
of thermal units of TANGEDCO and CGS were
used. TANGEDCO’s own hydro plants are
projected at actual PLF. For new Central and
Private Thermal Generating Stations average PLF
of 85% is used. Hydro stations are projected at 50%
PLF whereas the RE (Solar and Wind) units are
projected at 7% PLF.
TANGEDCO’s own thermal units have been
projected as per the estimates provided by
TANGEDCO.
Figure 7: Energy available from various sources
(MU)
Further, plants which have high power purchase
cost have not been considered. For estimating the
peak available, NEP norms were used.
Auxiliary energy consumption of all state thermal
and hydro stations including pumping energy for
Kadamparai Pumped Storage Plant is estimated at
8.4% (FY16 value).
It can be seen that the due to addition of plants in
the state the renewable energy share is expected
to remain at the level of 15-16% during FY17 to
FY19.
4.5. Key Issues
Coal Allocations and Availability.
As per the terms of the FSAs the linkages from
indigenous coal fields are to the order of 19.55
MMTPA for FY2015-16. Against this linkage,
TANGEDCO has received about 15.50 MMTPA in
FY2015-16. This shortage between linkage and
actual availability is due to multiple reasons.
TANGEDCO has requested The Ministry of Coal
and Ministry of Railways to arrange for suitable
solution to resolve the issues in supply and
transportation of full quantum of indigenous coal as
per FSA.
TANGEDCO is allocated BOBRN (Bogie Open
Bottom Release) type wagons for transporting coal
from Talcher mines to Paradip Port. Allocation of
wagons by Railways is not sufficient to cater to the
requirements of TANGEDCO resulting in less
realization of coal against the linkage quantity.
TANGEDCO has periodically taken up the short
supply of rakes issue with top officials of East Coast
Railways (ECoR)/Bhubaneswar. As per daily
programme, ECoR has to allot approx. 10 BOBRN
rakes/day from Talcher coal fields.
Further, TANGEDCO has also been allocated
approximately 2 BOXN rakes for supply of coal to
MTPS II (FSA 2012) from Talcher mines. This type
of wagon is suitable for unloading via wagon tippler,
however due to various reasons the wagons are
unloaded manually which causes delays and
ultimately lesser realization of coal against the
linkage quantity. Since the landed cost of coal
received from Talcher is cheaper than the landed
cost of coal received from ECL/Haldia and MCL/IB
Valley, TANGEDCO requested CIL to supply the full
linkage quantity from Talcher sidings. TANGEDCO
received only 105.24 Lakh Tonnes (LT) of coal

against the linkage of 152.24 LT form Talcher
sidings for the FY2015-16, with realization of 69%
only.
Further, for FY17 (upto Oct 2016), TANGEDCO has
received only 43.35 LT of coal against the linkage
of 87.28 from Talcher Sidings. This is about 50% of
the total linkage.

5. Transmission Plan
5.1. Transmission capacity requirement
The planning and development of intra-state
transmission system in the state is undertaken by
Tamil Nadu Transmission Corporation
(TANTRANSCO). A well planned and strong
transmission system will ensure not only optimal
utilization of transmission capacities but also of
generation facilities and would further facilitate
achieving ultimate objective of cost effective
delivery of reliable power to end consumers.
The requirement of electricity in energy and peak
demand (Including wheeling energy) for the State is
expected to increase from the present level of
1,00,319 MU and 14,533 MW in FY16 to 1,17,487
MU and 17,651 MW in FY19.
The state’s generation plan as detailed in previous
Chapter of this report outlines the upcoming
projects in the state in addition to the allocation from
central stations and other licensees. A total of 7,609
MW is expected to be added to the existing system
by FY19 for meeting the peak demand requirement
of 17,651 MW. The existing transmission system is
adequate for evacuation and transmission of power
and the transmission plan proposed in this chapter
aims at ensuring adequacy of transmission
infrastructure for evacuation of such power from the
inter-state boundary and proposed generating
plants within the State to the end consumers
located across various geographies of the State.
5.2. Existing Transmission System
Intra-State Transmission System
The intra-state system is maintained and operated
by TANTRANSCO, which is a subsidiary of TNEB
Limited. The company was formed when the
erstwhile Tamil Nadu Electricity Board was
restructured in Nov, 2010 into corporate entities.
As on 31.03.2016, TANTRANSCO operates and
maintains a transmission network of 30,331.6 ckm
of Extra High Voltage Transmission lines along with
908 sub-stations (400/230/110/66 kV) having total
transformation capacity of 59,953 MVA, spread
over the entire stretch of the State of Tamil Nadu.
The existing transformation capacity and line length
(400kV, 230 kV, 110 kV, 66 kV) of TANTRANSCO
network is summarized in Table 17.
The availability of TANTRANSCO’s transmission
system is at par with other leading state
transmission utilities in the country. However, the
existing capacity of intra-state transmission system
is enhanced year by year for meeting the demand
in the State.
Inter-State Transmission System
The interstate transmission system is operated and
maintained by PGCIL. The present inter-state
network consists of 8,127 ckm of lines and 9,300
MVA Substations.

The inter- state power systems in the Southern
region connect the various Central Sector
Generating Stations located in different states in the
Southern region to the rest of the states within the
region. The inter-state links connecting Tamil Nadu
to various nearby states are listed in Table 20.
Further, Table 19 shows the inter-state and intra –
state sub-stations at 400 kV and above level in
Tamil Nadu. Augmentation of transformation
capacity at substations with 1x500 MVA
transformers each is being implemented at Arasur,
Karaikudi, Madurai, Melakottaiyur
(Kalivanthapattu), Pugalur, Tirunelveli & Trichy
substations. The augmentation works at Trichy,
Madurai and Pugalur is expected to complete by
February 2017. Whereas Melakottaiyur
(Kalivanthapattu) is expected by December 2016.
The remaining three SS (Arasur, Karaikudi and
Tirunelveli are expected by FY20 (April 2019)
The following two new EHV substations are under
planning/construction:
a) 400/230 Tirunelvelli PS with 2x500 MVA
transformers
b) 765/400 kV Dharmapuri (Salem New) PS. This
PS is initially proposed to be charged at 400 kV and
will act as a pooling station.
5.3. Intra-state Transmission Plan
Ongoing schemes
TANTRANSCO is working on a number of intra –
state transmission projects with the financial
assistance from Government of India and financial
institutions such as JICA, KfW, REC and PFC to
improve the network infrastructure and to ensure
reliability and quality of supply to end consumers.
TANTRANSCO has identified such projects in order
to meet the following requirements

a) Meeting demand for power arising from
existing and future end-consumers in various
load centers/ pockets in the state;
b) Providing connectivity for evacuation of power
from various upcoming intra and inter-state
power plants and for onward delivery of such
power to load centers/ drawl points;
c) Improving the availability and reliability of the
intra-state transmission systems in the State;
and
d) Improving availability of intra-state
transmission systems to integrate existing and
upcoming renewable energy sources in the
state.
The plan covers system for intra-state transmission
network strengthening as well as evacuation of
power from State owned generating stations. The
summarized list of ongoing, approved and
proposed capacity additions at various voltage
levels is summarized in Table 21.
The substation and line wise details of ongoing,
approved and proposed intra-state transmission
systems have been provided in the annexures (8-
11).
Out of the 136 proposed substations, the ongoing
schemes for 50 sub-stations and 2,516 kms of
transmission lines were scheduled to be completed
by FY17. While about 86 Substations are scheduled
to be completed in the period FY18 to FY19. This
includes two substations of 765 kV with total
transformation capacity 7,500 MVA is expected to
be available by FY19. Apart from the above, under
Renewable Energy category 8 Nos. of substations
of 8,640 MVA capacity are expected to be available
by FY19. About 7,205 ckt km of lines are expected
to be added to the system by FY19. This investment
plan is rolling in nature and is subject to change on
account of variations in load flows through the
transmission network elements that may result from
deviations in load growth projection vis-a-vis actual
load growth.
TANTRANSCO is focusing on efficient operation
and maintenance practices to provide stable and
quality power with maximum transmission system
availability and minimum transmission system
losses.

5.5. Renewable Energy integration schemes
The state has made significant achievements in
addition of renewable energy sources in to the grid.
With such large capacities of renewable power,
especially wind energy, there is an ever increasing
demand for network connectivity. While most of the
connectivity requirements are of intra-state
corridors, the inter-state network also needs to be
strengthened in view of the demand for inter-state
open access for the RE plants in the state.
In view of this the following projects are being under
taken to strengthen the inter-state network:
400 KV SS at Samugarengapuram with 400kV
DC line from Samugarengapuram to Udangudi
Pooling station proposed during FY20.
Three more 230/110 kV Substations with a
capacity of 3X100 MVA each are proposed in
Muppandhal, Poolavady and Kongalnagaram.
These are expected to be operational by FY20.
Further, DPR for REMC has been prepared. The tender
for REMC in southern region has been floated by PGCIL.
Tenders were invited under 2 stage bidding. Stage-
1 technical discussion is proposed during the first
week of December.
5.6. Adequacy of Transmission Planning:
The intra-state transmission plan prepared by
TANTRANSCO is adequate to meet the projected
demand by FY19. The total capacity (including
existing GSS and Lines) after implementation of all
schemes is shown in Table 21
With the total anticipated demand for power
reaching 17,651 MW in FY19, the ongoing/
proposed projects for capacity additions and
augmentations will be adequate to cater to the
increasing load and also improve reliability of the
system by building in redundancies in the system.
With the proposed capacity additions it is envisaged
that there should not be any bottlenecks in
transmitting power from various generating stations
up to 110 kV network of TANTRANSCO, provided
the identification of sub-station locations has been
done in accordance with the detailed district/ area
wise load growth assessments prepared by
TANTRANSCO.
5.7. Fund Requirement (Intra-state only)
TANTRANSCO has made a layout of Rs. 20,309
Cr. This amount includes investments of Rs 4,107
Cr. on connecting RE projects in the state to the
grid. TANTRANSCO has projected investments of
Rs. 16,202 Cr. for extending the transmission
network in the state to cater to the growing demand
in the state. The year wise fund requirement is
shown in Table 22 below.
An amount of Rs. 6,104 Cr. is expected as loan
from REC, Rs. 5,424 Cr. from PFC, Rs. 3,257 cr.
from JICA, Rs. 1,698 Cr. from KfW, Rs. 1,192 Cr.
from Other agencies such as TNIPP, NABARD etc.
It will be ensured that the balance amount of Rs.
2,633.41 Cr. will be tied with funding agencies
before taking up the work.

6. Distribution Plan
6.1. Objectives of the distribution plan
Distribution of electricity in the state is managed by
the state distribution utility – TANGEDCO. It is the
sole distribution licensee in the state. The company
was formed in 2010 when the erstwhile TNEB
limited was restructured into corporate entities.
During the period FY16 to FY19 the peak demand
(including wheeling demand) and energy
requirement (including wheeling sales) is expected
to increase from 14,533 MW and 1,00,319 MU in
FY16 to 17,651 MW and 1,17,487 MU in FY19.
This is due to increase in natural demand from the
present consumer base and more importantly
because of the initiatives proposed under this PFA
Roadmap which aims to maintain 24X7 supply to all
consumers in the state. This would require
commensurate investments in the sub-transmission
and distribution infrastructure.
Accordingly, the objectives of the distribution plan,
in accordance with the 24X7 PFA objectives,
includes the following:
a) Maintaining 24X7 supply to all connected
consumers through capacity augmentations
and building redundancies in the upstream
network for improving reliability of supply;
b) Maintaining 24X7 supply to cater to increase
in demand from existing consumers and
increase in demand owing to new consumer
growth in the State;
c) Provision of investments for improvement in
Quality of Supply for all categories of
consumers
d) Making system improvements for reducing
AT&C losses in accordance with the targets
agreed with MoP; and
e) Adopting appropriate technologies and
systems to support RE integration and EE/
DSM measures in the State.
6.2. Existing Distribution System- TANGEDCO
The distribution network of TANGEDCO comprises
of 66 kV, 33 kV, 22 kV and 11 KV sub-transmission
system. This forms the distribution backbone at the
district level and LT distribution systems and
delivers electricity to majority of the end consumers.
An overview of department’s network infrastructure
in terms of installed transformation capacity and line
lengths of feeders at various voltage levels is
provided in Table 24 below.

Tamil Nadu has made significant improvement in
village level electrification as the state was one of
the primary states in India to achieve 100% village
electrification level. This is further fortified by the
fact that the HH electrification in 2011 was 93.4%
DTR Failure rates
TANGEDCO’s Distribution failure rate for FY15 was
4.27%. A part of the investments in network are
planned to bring down the DTR failure in the state.

Metering
TANGEDCO has 31.97 Lakhs unmetered
consumers as on March 2016. This corresponds to
12% of the total consumers of 2.70 Crores. All of
the 31.97 lakhs consumers belong to only two
categories
Agriculture and Govt.seed farm etc.
Huts in Village panchayats, TAHDCO etc.
TANGEDCO is preparing a metering plan at DTs
associated with unmetered consumers to estimate
the sales to these consumers.
TANGEDCO is aiming for introduction of modern
metering technology for all its consumers. A
quantum of consumers have been included under
DDUGJY and IPDS for replacement of meters.
TANGEDCO seeks GoI support for meeting the
financial requirements for upgrading/replacing
meters for the remaining consumers.
SAIFI SAIDI
TANGEDCO is monitoring SAIFI and SAIDI values
of the R APDRP towns in the state. As per the latest
(Aug 2016) report covering 63 towns and 273
feeders, SAIDI is 2:20 hrs/month (Rank 1 in India
as per URJA app) and SAIFI is 3.47. It may be
noted that the systems of monitoring are still being
updated and the values may not represent the
actual status in the towns. Town wise SAIFI and
SAIDI values are provided in Annexure 19.
AT&C Loss
AT&C loss including ~4% Transmission Loss for the
state during FY10 to FY16 suggests that losses had
increased in FY11 to 24.95% from 21.53 % in FY10,
however due to AT&C loss reduction measures
taken up by the utility the present AT&C loss in
FY16 is 20.91%. (Losses are aggregate of
distribution and transmission system in the state)
Figure 12: AT&C Loss trend for FY10 to FY16
TANGEDCO further is taking full efforts to reduce
the AT&C Loss to a target level of below 15% by
FY19 through distribution strengthening works
under the R-APDRP Scheme (Part B) and by
ensuring formation of enforcement squads to curb
theft of energy. Action is also being planned to be
undertaken on any information received about theft
of energy followed by conducting surprise checks,
raids, etc. on consumer premises.
The activities to be undertaken are detailed in the
following figure.

6.3. Central and State Government Schemes
The collective objective of all the Central/ State
Government schemes has been to enhance the
reach, reliability and quality of electricity to end
consumers and to improve the financial position of
utility by way of reducing the AT&C losses. The
following schemes are presently underway and are
at various stages of implementation in Tamil Nadu,
which not only provide the funding assistance but
also aim towards enhancing the technical capacity
of utilities.
RGGVY
RGGVY XI plan: TANGEDCO has completed field
works in 26 districts of Tamil Nadu and financial
closure of the total approved amount has been
achieved.
REC has accorded sanction for the implementation
of the RGGVY scheme in balance 3 districts viz.,
Nilgiris, Tirunelveli and Dharmapuri districts on
23.12.2011 at a total cost of Rs.37.27 Cr. under XI
plan phase-II. Works under the phase II of XI Plan
are being carried out and 31% (Rs. 11.47 Cr) of the
approved DPR cost (Rs. 37.27 Cr) have been
disbursed.
Based on the increase in award cost from the
sanctioned cost, approval accorded by REC on
10.10.2013 for an amount of Rs.41.46 crores.
About 640 Nos. of 16 and 25 KVA Distribution
Transformers and about 2,654 Kms of HT/LT
distribution lines are sanctioned by REC for
effecting service connections to 24,369 BPL
households in these 3 districts and above works are
under progress.
Remote Village Electrification
Currently 115 Nos. un-electrified remote habitations
with a total of 5,787 households have been
identified for electrification through RE sources.
Due to the remote location of these habitations,
conventional mode of electrification through
TANGEDCO grid is not feasible
These habitations are being included in the Remote
village electrification program of the State
Government Scheme. These households are
proposed to be electrified through standalone
Rooftop Solar PV systems. Contracts have been
awarded and works are in progress.
R-APDRP- Part A and SCADA
The total approved amount for RAPDRP Part A is
Rs.417 Crores. The proposed investments are in
the field of Information Technology implementation.
Part A schemes covers 110 towns (with 30,000
population as per 2001 census) and Rs.182.17
Crores for SCADA / DMS implementation in 7 towns
(having a population of 4 Lakhs consumers and
annual consumption of 350 MUs) have been
sanctioned and the works are expected to be
completed by March 2017 and December 2016
respectively.

7. Renewable Energy Plan
7.1. Introduction
The state of Tamil Nadu is blessed with various
forms of renewable energy sources viz., Wind,
Solar Biomass, Biogas, Small Hydro etc. The state
has emerged as a major hub for development of
renewable energy in the last few years and
presently approx. 40% of the total installed capacity
in the state is from RE sources.
The Govt. of Tamil Nadu set up the Tamil Nadu
Energy Development Agency (TEDA) in 1985 to
promote the use of new and renewable energy
sources and promote energy conservation activities
in the state. The credit for such large capacity
additions is attributable to the enabling policy
framework promulgated by the state govt. and
effective implementation of projects.
The Hon’ble TNERC notified the RPO obligations
for the state in 2010 providing the framework for the
obligated entities to meet their renewable
requirements through RE sources and/or RE
certificates. On similar lines, the state govt. issued
the Solar Energy Policy -2012 outlaying its vision of
solar development in state and the targets over the
coming years in addition to providing incentives and
promotions to solar technologies and R&D in solar
industry. The Renewable Purchase Obligations
(RPO) and Solar Purchase Obligations (SPO) for
the distribution licensee for the last five (5) years
are shown in Table 31 below:
Table 31: RPO Targets for Tamil Nadu
Year RPO SPO
FY 12 9.00% 0.05%
FY 13 9.00% 0.05%
FY 14 9.00% 0.05%
FY 15 9.50% 0.5%
FY 16 11.50% 2.50%
FY 17 14.00% 5.00%
Note: RPO targets are inclusive of SPO
The state has an estimated potential of 15,000 MW
in Solar and 14,000 MW in wind (as per NIWE-
CWET). The renewable energy addition proposed
over the next five years is shown in Table 32. It is
envisaged that the proposed investments on solar
and wind shall be from the private sector only.
Based on the Tamil Nadu Solar Energy Policy
2012, Solar Net Metering concept has been
implemented in the state of Tamil Nadu.
TANGEDCO is encouraging establishment of
HT/LT grid – interactive roof top solar power plants
for captive use. Solar pumps for Agriculture
connections are also being implemented by TEDA
and agricultural department. Further, under
preferential tariff route for solar power, so far,
TANGEDCO has executed power purchase
agreements (PPA) with 86 developers for a
combined capacity of 1,484 MW for the year 2015-
16. Out of 1,484 MW, 948 MW have been
commissioned under this scheme as on
01.09.2016. Under Rooftop scheme a combined
capacity of 54.97 MW have been commissioned.
Under REC scheme, 66 solar plants having a total
capacity of 120.152 MW have been commissioned.

The state has some ambitious schemes for
promotion of RE based energy sources viz. CM’s
Solar Powered Green House Scheme, CM’s Solar
Rooftop Capital Incentive Scheme, Wind Solar
Hybrid System and small hydro/micro hydel
projects. Under the state’s REC scheme, 66 Solar
Plants having total capacity of 120.152 MW have
been commissioned so far. Under the state
preferential tariff scheme, solar PV projects are
allowed to be set up at a tariff of Rs. 7.01 (without
AD) and Rs. 6.28/kWh (with AD) during the control
period. Similarly solar thermal projects shall attract
a tariff of Rs. 11.03/kWh (without AD) and
Rs.9.88/kWh (with AD). Details of the existing Solar
and wind capacity in the state is provided in Table
34 and Table 35 below respectively. It is observed
that the entire solar capacity in the various districts
is privately owned.

7.3. Capacity Additions – RE Plan
Table 36 below depicts the capacity addition plans
in the renewable energy categories for the years
FY17 to FY19. As per the projected figures, 5,265
MW is expected to be added through RE Sources.
7.4. Funding requirement
It is observed that most of the RE capacity additions
shall be done by private entities. Based on the
information available from the state, the proposed
investments on solar and wind sectors shall be from
private sector only. Fund requirement details for
development of intrastate transmission
infrastructure for evacuation of upcoming
renewable energy sources is discussed in Section
3 of this report.
7.5. RE plan-Issues
The state is not facing major issues related to
renewable energy projects. This is seen form the
recent developments in installed capacity of RE
projects. Most of the projects are being funded
through private participation so there is limited
financial involvement from state owned agencies. It
may also be noted that the regulatory provisions for
promotion of Renewable projects are in place and
no major policy related intervention is identified.

8. Energy Efficiency Plan
8.1. Energy Efficiency Plan
As per the provisions of the Energy Conservation Act
2001, the State Designated Agency (SDA) i.e the
Tamil Nadu Electrical Inspectorate (TNEI) has been
nominated by the Bureau of Energy Efficiency (BEE)
in consultation with the state govt. to carry out
schemes on energy conservation and other allied
activities in the state of Tamil Nadu. The role of SDA
is to create general awareness among masses on
benefits of energy conservation measures and to
institutionalize the energy efficiency project
implementation in domestic, commercial and
industrial segments.
TANGEDCO, being the state’s utility, is engaged in
various energy conservation activities and
awareness programs for ensuring energy efficiency
in all segments.
The Energy Department vide orders in 2008 and
2010 have mandated implementation of energy
conservation measures in all govt. buildings and
offices including local bodies and public sector
undertakings and have banned the usage of
incandescent bulbs. Further during 2012, the
Government has ordered usage of LED lamps in
locations such as path ways, entrances, corridors,
rest rooms etc. and Electrical equipment and
appliances with minimum 3 star rating label to be
procured and installed in the Government offices and
buildings.
Energy Conservation day is celebrated on December
14th of every year and Energy Conservation week
from December 14th to December 20th in order to
create awareness to the public on the importance of
Energy Conservation.
The following schemes were taken up by
TANGEDCO as a part of its initiative for energy
efficiency measures.
a) Distribution of about 8.75 lakh nos. CFLs to
hut services in exchange of Incandescent
bulbs (ICBs) across the state.
b) Distribution of 149 nos. of Energy Efficient
Pump Sets (EEPS rated 4 star & above) to
willing agricultural consumers in replacement
of existing inefficient old pump sets.
c) Have mandated the use of EEPS (4 star &
above) for new agricultural service connection.
8.2. Energy Efficiency Action plan
TANGEDCO has been selected under BEE's
Capacity building of DISCOMs program to establish
the energy saving potential in various sectors by
conducting load research across the state. The
selection of consultant for conducting the load
research has been completed. The Load Survey in
all consumer categories including domestic,
commercial, industrial, educational institutions etc
have been completed. The draft report of this load
survey is under preparation by the appointed
consultant.
Based on the report on load survey, a DSM action
plan will be formulated for maximizing the use of
energy efficient appliances under various sector wise
schemes. TANGEDCO will take up the schemes for
implementation, one by one, subject to financial
viability.
Distribution of 1 crore LEDs comprising of 2 LEDs
per household at a subsidized rate of Rs.10/- per
LED to all metered domestic services (consuming
less than 500 units bimonthly) in five cities viz.
Chennai, Coimbatore Madurai, Trichy and Tirunelveli
is under consideration. Based on the outcome, this
scheme will be extended to other parts of the state.
Under EESL’s UJALA program, institutional
distribution of LED lights have been done by EESL.
In this program 61,018 LEDs have been distributed
to Railways in Tamil Nadu. LED distribution for all the
HHs in the state would be carried out after finalization
of the load research and approval of The State
Government.
The state government has undertaken a scheme to
replace all the street lights under municipal
Power for All – Tamil Nadu
Page | 39
corporation and municipalities in the state with LED
street lights. This will reduce the street light demand
by 35%. The total cost of this project is about Rs. 300
Cr.
8.3. Fund Requirement and action plan
On receipt of the draft report from the consultant,
suitable schemes can be formulated under the DSM
action plan.
Based on the schemes to be taken up for
implementation, fund requirement can be
established.

9. Financial Position of Utility
(TANGEDCO)
9.1. Introduction
The restructuring of erstwhile Tamil Nadu Electricity
Board (TNEB) was completed in year 2010 with
establishment of a holding company, TNEB Ltd and
two subsidiary companies, namely Tamil Nadu
Transmission Corporation Ltd (TANTRANSCO) and
Tamil Nadu Generation and Distribution Corporation
Ltd (TANGEDCO). Unlike other States, the
restructuring plan provided a restated balance sheet
for both TANTRANSCO and TANGEDCO. The
accumulated losses of erstwhile TNEB to an extent of
Rs.34,741.35 Crs has now been adjusted in the final
transfer scheme notified vide GO MS No.49/13.08.15
by revaluation of assets to an extent of Rs.54,658.71
Crs. and the excess revaluation reserve of
Rs.12,265.99 crs., Rs.7,163.58 crs., and Rs.487.79
Crs. transferred to TANGEDCO, TANTRANSCO and
TNEB Ltd., respectively.
Owing to a long haul of non-revision in tariffs,
subsequent increases in tariff, even though
significant, weren’t adequate enough to revive the
dwindling finances of the utility and TANGEDCO
continued to post significant losses. As an impact of
above, the ratings of TANGEDCO have taken a
severe hit and the utility has been rated as “B” by
ICRA, indicating “Below Average Operational and
Financial Performance Capability”. This is based
from the past performance of the utility, wherein it has
reported net losses of Rs 13,985 Cr. These ratings
derive their support from the high financial risk profile
arising from cash losses, poor capital structure and
debt protection measures. Dependence on tariff
subsidy from state government has increased
substantially. However, the tariff hike announced by
TNERC in December, 2014 and implementation of
Financial Restructuring Plan (FRP) have been the
key areas of support for TANGEDCO to start
addressing the pain areas.
9.2. Commercial & Financial Viability
The operational and financial performance of
distribution utilities often determine the health of
power sector in a State. One of the key indicators of
commercial health and resultant financial position of
a distribution utility is the gap between average cost
of supply (ACS) and average billing rate (ABR).
In case of TANGEDCO, gap between ACS and ABR
has decreased to Rs.1.09/kWh in FY16 from Rs.
2.33/kWh in FY11. This reduction of gap has been
possible only with the tariff increase over the last 3-4
years. There is substantial dependence of state utility
on the State Government, which is bound to increase,
if timely corrective measures are not adopted. The
government support in form of revenue subsidy has
increased over three folds to Rs. 6,695 Cr. in FY16.

Figure 15: Accumulated Losses in Rs. Cr.
Figure 16: Projected AT&C Loss trajectory (%) and energy input (MU) - TANGEDCO
Some of the key factors contributing to the
commercial and financial situation of TANGEDCO
are a weary consumer mix and looming AT&C losses.
The consumer mix of TANGEDCO is skewed towards
agricultural and domestic consumers which are
highly subsidized. Together these two consumer
categories account for over 46% of its annual sales.
The share of subsidizing consumers, especially
industries is lower than 10% of annual sales, thus
leaving a wide gap between the ACS and ABR of the
utility.
AT&C losses is another crucial parameter affecting a
utility’s financial performance. In case of
TANGEDCO, the high levels of distribution losses
has led to increase in gap between ACS and ABR.
During the last 4 years the AT&C losses have been
in the range of 24% to 25%(including Transmission
losses), which have reduced to 20.91% in FY16.
Going forward, the utility has planned to achieve
target of reducing AT&C losses to 14.4%(excluding
transmission losses) by FY19, form the existing level.
Figure 16 presents the existing and projected AT&C
losses and corresponding energy requirements of
TANGEDCO. It may be observed that the AT&C
losses in FY16 had reduced considerably to nearly
17%(excluding transmission losses).
TANGEDCO has undertaken distribution
strengthening works under the Government of India
Scheme of R-APDRP Part B with a total project cost
of Rs. 3445.10 crores. Part-B Schemes cover New
SS, Transformers /Transformer Centers, Re-
Conductoring of lines at 11/22 kV level and below,
Load Bifurcation, Feeder Bifurcation, HVDS, RMUs,
APFC Panels, Sectionalisers, installation of capacitor
banks and consumer meter replacement etc., in order
to reduce the AT&C losses to the target level of 15%
in the eligible project towns (with AT&C losses of
above 15%).
TANGEDCO is taking full efforts to curb theft of
energy and the following squads have been formed
for detection of theft:
a) Seventeen Enforcement squads, headed by
Executive Engineer in 4 divisions in Chennai,

c) Forty (40) teams comprising Ex-Serviceman
(5 members per team) are also functioning
along with the existing 18 Enforcement

d) Immediate action is being taken on
information received over phone call (or)
anonymous petitions about theft of energy.
e) Further surprise check, night raids and mass
raids are also conducted in the consumer
premises to curb theft of energy.
With widening of gap between ACS and ABR,
increased AT&C losses and non-revision of tariffs,
the financial position of TANGEDCO has worsened
over the years. The reported financial losses of
TANGEDCO have been growing consistently during
the last few years from Rs. 5,634 Cr. In FY11 to Rs.
12,757 Cr. in FY15. TANGEDCO commenced its
operation without any accumulated losses, as the
entire accumulated losses had been wiped out
through the re-valuation results created in the
process of final transfer scheme. However, in FY15,
the accumulated losses have multiplied from Rs
18,955 Cr in FY12 to Rs. 55,821 Cr in FY16. The YoY
profits recorded and rising accumulated losses of
TANGEDCO are presented in Figure 15.
In addition, during the past few years, TANGEDCO
has committed significant capital expenditure for its
network expansion. In the past five (5) years, a total
of Rs. 9,425 Cr. has been undertaken as capital
expenditure investments. In order to fund its
investment requirements and to a large extent the
losses as well, the utility has resorted to significant
market borrowings. The long term debt of
TANGEDCO has increased from Rs.19,412 Cr. in
FY11 to Rs.67,194 Cr. in FY15. On account of higher
reliance on long term as well as short term funds to
meet capital and revenue account deficits, there has
been a sharp rise in interest burden, resulting in
weakening of debt service indicators.
Considering the precarious financial position, with
surmounting losses, heavy dependence on debt to
fund the operations and significant burden on the
state government for subsidy, the utility has already
gone for a Financial Restructuring Plan (FRP) in
2012. The details of FRP are discussed below.
9.3. Financial Restructuring Plan
Owing to degrading financial health of the state
distribution companies, the Government of India
constituted an expert committee to suggest a strategy
for financial Restructuring Plan (FRP) of utilities. The
guidelines were framed stipulating takeover of 50%
of short term liabilities (STL) as of March 31st 2012
by the State Governments and balance 50% of short
term liabilities to be rescheduled by lenders and
serviced by the DISCOMS.
In line with above, TANGEDCO prepared a FRP with
an objective to improve its financial sustainability,
which was finalized and approved by the state
government in December 2012. The key aspects of
FRP were as below.
As per the FRP, the GoTN has issued special
securities of Rs.1,000 crores during 2014-15 and
Rs.1,000 crores during 2015-16 and also
redeemed to the Banks.
The remaining FRP to the extent of Rs.4,353.49
crs. is expected to be taken over before the end
of FY2017-18. During the current financial year
2016-17, the GoTN has provided a sum of
Rs.2,000 crs. for this purpose.
As per FRP, 25% of the loss taken over by GoTN
has to be contributed as Grant from GOI and the
same was not so far released from GOI.
Similarly the cash loss funding from certain
banks was not yet sanctioned and released to
TANGEDCO to the extent of Rs.160.37 crs.
Since the banks are committed to fund the
projected loss for the years 2012-13’ 2013-14
and 2014-15 under FRP, the delay by the banks
is not agreeable. Further the banks are not
extending any loan to TANGEDCO from 2015-
16 onwards, due to the restructuring process
implemented under FRP.
Under FRP, the commercial banks will not
extend any further short term loan to
TANGEDCO to meet operational commitments
caused by gap in ABR and ACS from FY16
onwards. Though there is a provision to fund the
losses beyond projections by the state
Government. However, the Government of Tamil
Nadu could not accommodate the loan
assistance in view of the Fiscal Responsibility
and Budget Management (FRBM) restrictions.
TANGEDCO has submitted a proposal seeking
the following relaxations and modifications in
Power for All – Tamil Nadu
Page | 43
FRP for the long term financial improvement of
the Power Sector in the state
o Funding differential loss for the year 2013-
14 and 2014-15.
o Extension of funding period from 2015-16 to
2018-19
o All the new loans may be sanctioned with a
tenure of 15 years with an initial moratorium
of 5 years.
However the Reserve Bank of India in its recent
letter dated 14.8.2015 has expressed concern
on TANGEDCO’s huge outstanding loans of
Rs.17,818 crores with banks as on 31.3.2015
and urged the GoTN to take over the loans of
TANGEDCO by relaxing FRBM restrictions as a
special measure.
Thus, going forward TANGEDCO not only faces a
challenge of managing its high level of debt burden
but also achieving high levels of efficiency to
minimize disallowances and adequately meet its
ACS. It is imperative that these factors may be
considered carefully for the financial projections of
TANGEDCO which are discussed in the following
sub-section.
9.4. Financial Projections
In order to estimate the impact of PFA program on
the financials of a utility, it is pertinent to assess the
incidental cost of the program vis-à-vis the potential
of generating additional revenue due increase in
energy sales. As the utility progresses on achieving
reduction in AT&C losses, the gap between average
cost of supply and average realization is expected to
shrink. In line with above, an analysis has been
carried out to assess the cost impact of PFA program
on tariff as well as financials of the utility. Table 40
presents the assumptions which form the basis for
such projections.

The impact of PFA program on the Tariff structure
prevalent in the state is reflected in Table 43 as
below. This impact is due to per kWh gap of incidental
cost of providing additional power and revenue
generated due to increase in energy sales. The
impact on tariff due to PFA capital expenditure is
expected to remain in the range of Rs. 0.29/kWh in
FY17 to Rs.0.53/kWh in FY19.
The key reason behind the marginal increase in tariff
impact is the reduction in overall average realization
as the share of domestic category sales increases,
but the constituents of ACS, other than power
purchase cost continue to increase. The additional
cost on account of capital expenditure accounts for a
considerable increase in ACS.
Therefore, in the base case, the financial statements
of TANGEDCO have been prepared considering that
the per unit power purchase cost and tariff shall
remain at the present levels, while the impact of other
incidental cost is accounted.
As can be seen in the P&L statement, the financial
losses of Rs. 5,787 Cr. in FY16 are likely to increase
to Rs.10,312 Cr.in FY19.

9.5. Scenario Analysis
Any change in tariff or under achievement of AT&C
losses considered for the base case or non-
availability of funding in form of grants will translate
into additional impact on the financial position of the
utility. The impact of existing accumulated losses of
TANGEDCO or the impact of purchase and sale of
surplus power available to TANGEDCO also need
to be evaluated. Therefore, analysis under following
scenarios have been carried out:
1. Increase in tariff to ensure that utility becomes viable by FY19
2. Non-Availability of grants under the schemes where DPRs are not finalized (available only to the extent approved as per DPR) to fund the capital expenditure.
Power for All – Tamil Nadu
Page | 47
3. Under achievement of AT&C loss targets: considering same T&D loss level as in FY15, till FY19
Scenario 1: Increase in tariff required for the utility to become viable
As existing gap between average cost of supply
and average realization is significant, an increase
in tariff may be required immediately. Table 45
summarizes the underlying assumptions. In order
to achieve financial viability by FY19, the utility
requires an annual tariff increase of 5.52%, in
addition to complete pass through of increase in
power purchase cost. The assessed tariff impact is
expected to recover the costs and the utility will be
able to become financially viable having positive
PAT (YoY) by FY19. The resultant P&L account
under this scenario is presented in Table 46.

The projected cash flow statement till FY19 and
projected balance sheet is provide in Annexure 21
& 22. It can be observed from the cash flow
statement that with 5.52% tariff increase,
TANGEDCO is expected to post positive YoY cash-
flows by FY19.
Scenario 2: Non-Availability of grants (funding of capital expenditure through grants under various government schemes)
The dependence of utility on funding of the
proposed investments through various State and
Central Government schemes can be assessed by
the impact on utility’s finances under a scenario
where grant funding is not available. For the
ongoing schemes where the funds have already
been committed by the State or Central
Government, the grants are considered to be as
envisaged in the respective schemes. Table 47 on
the following page summarizes the key parameters
underlying the analysis and the impact on tariff has
been detailed in Table 48. As can be seen in Table
48, the impact on tariff is expected to increase due
to non-availability of grants to fund the capital
expenditure. The tariff impact for in such scenario
is estimated to range between Rs.0.30/kWh to
Rs.0.54/kWh. Table 49 presents the projected profit
and loss statement of TANGEDCO under this
scenario.

As can be seen above, the annual financial losses
of TANGEDCO are expected to increase to nearly
Rs. 10,529 Cr. in FY19 as against Rs. 10,312 Cr.
under the base case.
Further, as the utility’s cost of funding declines due
to availability of grants, the required tariff increase
to achieve the financial viability is likely to increase
to 5.63% p.a. as against 5.52% tariff increase
required in base case.
The projected cash flow statement till FY19 is
provided in Annexure 23 & 24.
Scenario 3: Under achievement of AT&C loss reduction trajectory
Power for All – Tamil Nadu
Page | 50
Base case analysis, scenario 1 and scenario 2
assumes the achievement of AT&C loss trajectory
by the utility. However, in case the utility misses
T&D loss reduction and is higher by 1% every year,
the impact on financial position is going to be
significant. Table 50 summarizes the key
parameters underlying the analysis in scenario 3.
There is an impact on tariff and is expected to be in
the range of Rs. 0.29/kWh to Rs.0.53/kWh. Due to
additional cost and under-achievement of T&D loss
trajectory there is an adverse impact on the
financials of the utility, as presented in Table 51. As
can be seen in Table 52 the annual financial losses
of utility are expected to increase to nearly Rs.
10,809 Cr. in FY19 vis-à-vis Rs. 10,312 Cr. in FY19
under base case, this indicates that TANGEDCO
needs to focus on AT&C loss trajectory.
It may also be important to note that in this scenario,
the funds available as grants under centrally
sponsored schemes (IPDS, DDUGJY) are
restricted to 60% of project value.
The required tariff increase to achieve the financial
viability by FY19 is higher at 5.78% as compared to
5.52% in base case.

Action Points for improvement in financial positions of TANGEDECO
TANGEDCO’s cost structure needs to be revamped in order to achieve financial independence and improvement in profitability margins. This may be achieved by reducing the input costs and increasing the revenue. The following action points describe the areas in which TANGEDCO may need to work:
1. Reduction in input costs: The input costs for the utility are effected by the following items: a. Own generation cost: One of the main components is the cost of coal. A part of
TANGEDCO’s coal requirement is met through imported coal. This puts additional pressure on TANGEDCO as they have to bear additional cost to ensure that power is available from its own stations. Further, non-availability of cheaper power in the market also adds to the woes of the utility. To reduce dependence on imported coal, for receipt of full linkage quantity from the Coal Companies against the available FSAs and increase of FSA quantum to 100% of the requirement for its existing and upcoming plants, TANGEDCO may highlight these issues regularly with appropriate authority such as MoC/Railways/Paradip Port.
b. Financing and Interest Cost: In FY15 TANGEDCO’s interest cost was about Rs.8,000 Cr.
This amount is attributable to long term and short loans taken by the utility to meet its financing requirements. In view of the huge interest burden of TANGEDCO, measures to decrease interest cost through availing refinances at reasonable rate of interest are being explored. The Tamil Nadu Power Finance Corporation (TNPFC) being one of the Government of Tamil Nadu owned utility extending loan assistance at cheaper rate of interest. Government of Tamil Nadu has advised various state owned public sector undertaking to divert their unutilised funds and matured deposits to invest in TNPFC for further funding to TANGEDCO, so that the power utility will save huge interest charges, besides managing the cash flow. Similarly, among the various loans with TNPFC, higher rate of interest bearing loans were pre-closed and further steps are also being taken up to prepay loans in the descending order of rate of interest. The utility may undertake an exercise of refinancing all or part of its debt. The utility may pursue authorities to seek reduction in interest amount of loans by PFC and REC. Further, the utility may also explore ways to increase the repayment period of loans. This may be instrumental in reducing the interest cost borne by the utility.
c. Reducing Power Purchase Cost: TANGEDCO has allocations from various central
generating stations and private stations besides operating its own station in order to meet the requirement of the state. The utility may be able to bring down its power purchase costs by efficiently managing the sources. TANGEDCO has already taken steps to replace the costlier sources of power by cheaper sources especially in case of private generating stations. Further, the utility buys power from some CGS with very high variable costs. The utility may explore means to replace such stations with medium or short term power from the open market in order to reduce the overall power purchase costs.
d. Availability of Hydro Stations: The current constraints in the inter-regional transfers have
restricted the utility’s ability to draw cheaper hydro power from surplus states. Once the inter-regional capacity is adequate, the utility may explore means for replacing the costly generation sources (own/private/central) with cheaper power available elsewhere in the country.
2. Increasing revenue: The gap between average billing rates is one of the major concern.
TANGEDCO may consider the following options for improving its revenue stream: a) Increase in targeted Subsidy: Currently, the subsidy declared by the government is at a
fixed rate. This amount is not sufficient to recover the cost of supply especially for the Agricultural consumers. TANGEDCO and GoTN may work towards providing subsidy at the cost of supply. This will help the utility to manage the cross subsidy requirement and help in rationalising the tariff structure for the state.
b) Increase in tariff: The scenarios in this chapter provide evidence that the utility may need
sustained tariff hikes across every consumer category. The utility may seek tariff hikes from the regulator based on its current deficit. Further, actions towards restructuring the tariff slabs will help in higher average tariff for the utility.
AT&C Loss reduction: The utility must ensure adherence to the AT&C loss reduction trajectory
proposed in this roadmap. Reduction in AT&C losses will help the utility to manage its financial gaps and further increase its revenue.
